It changes greatly with lifestyle habits
Summarized the characteristics of people at high risk
Three of the highest risks
Red and processed meat at least 5 times a week
Designated as a WHO carcinogen
Processed meat (ham and sausage) is particularly dangerous.

Maintaining proper weight is important.

検索で多いのが「大腸がんに気づいたきっかけ」。私の周り(外来での相談も含めて)で多い“受診につながったきっかけ”は、実は「強い痛み」よりも、地味だけど続く変化です。 まず一番多いのは血便。真っ赤な血が付く人もいれば、黒っぽい便(タール便っぽい)で気づく人もいます。「痔だと思って放置してた」「疲れてるだけだと思った」という声が本当に多いです。痔がある人でも、いつもと違う出方(量が増える・混ざる・続く)があれば要注意です。 次に多いのが便通の変化。便が細くなった、残便感がある、便秘と下痢を繰り返す、お腹が張る…など。「食生活のせいかな」と様子見しがちですが、2〜3週間以上続くなら一度相談して損はありません。慢性的な便秘が続いている人はリスクも上がるので、なおさら早めが安心です。 意外と見逃されるのが、原因不明の貧血や体重減少。健診でヘモグロビンが下がって「鉄剤出しておきます」で終わってしまうケースもありますが、特に男性や閉経後の女性の貧血は消化管の出血を疑うきっかけになります。 「症状がないから大丈夫」と思いたい気持ちも分かります。でも大腸がんは、症状が出る前に見つけられるのが強み。便潜血検査は年1回が基本で、陽性なら“痔のせいかも”と決めつけずに大腸内視鏡へ進むのが大事です。 さらに、当てはまる人は検診の優先度が上がります。赤身肉・加工肉を週5回以上、野菜・果物をほとんど食べない、運動習慣がない、毎日飲酒、喫煙、肥満(BMI25以上)、便秘が慢性的、家族歴がある、50歳以上、潰瘍性大腸炎やクローン病など慢性的な腸の炎症がある——このあたりは「自分の生活だ…」となりやすいポイント。 家族歴がある人は特に大事で、「親が50歳で発症なら自分は40歳から」など早め開始が目安になります。 最後に受診の目安。血便・黒い便、便が極端に細い、激しい腹痛、急な体重減少があるときは“様子見”をやめて早めに医療機関へ。内視鏡は検査でありながらポリープを取れて、がん化を防げることもあります。気づいたきっかけが小さな変化でも、行動につながるのがいちばんの予防です。
